2017 Highlights

01.29.18

The Estuary Partnership had a busy year! Here are a handful of highlights from 2017: Completed construction of two habitat restoration sites: In partnership with the US Forest Service, we restored a section of Hamilton Creek in Skamania County by adding 200 pieces of large wood to the creek to add habitat complexity, and revegetating the area with 9,000 conifers and willows. The East Fork Lewis River also got a rehab for salmon and steelhead, with an Estuary Partnership-led project that excavated a side channel to reconnect it to the East Fork Lewis mainstem. The project also added 200 pieces

Horsetail Creek Update

02.05.18

Our scientists were granted access by the U.S. Forest Service to enter the still-closed Horsetail Wetland Restoration site to investigate the project’s post-fire needs. Wearing hardhats and following the proscribed safety protocol, staff encountered localized areas of small ground fires in the 2013 western project area. Charred branches could be seen here or there, however, this downed wood only appeared to have smoldered and did not spread significantly. As a whole, the 30 acres of riparian plantings installed during the project were not compromised and the staff were heartened to see the

Bi-State Program, Additional Reports. Bacteria Studies, Sep-Oct 1992 & Nov-Dec 1992.

02.21.18

September - October 1992:High enterococcus bacteria counts detected during a reconnaissance survey in 1991 indicated a possible public health risk in the lower Columbia River. The purpose of this project was to determine if a chronic public health risk exists during high contact recreation periods due to bacteria contamination. Ecology sampled twelve stations between the mouth of the Columbia River and river mile 170 (Hood River) weekly- from September 1 to October 12, 1992. Fecalcoliform and enterococcus bacteria were monitored, as well as oxygen, temperature, pH, and conductivity. Water

Columbia Estuary Data Development Program - Abstracts of Major CREDDP Publications

02.22.18

This document is one of a set of publications and other materials produced by the Columbia River Estuary Data Development Program (CREDDP). CREDDP has two purposes: to increase understanding of the ecology of the Columbia River Estuary and to provide information useful in making land and water use decisions. The program was initiated by local governments and citizens who saw a need for a better information base for use in managing natural resources and in planning for development. In response to these concerns, the Governors of the states of Oregon and Washington requested in 1974 that the

Columbia Estuary Data Development Program - Avifauna of the Columbia River Estuary

02.22.18

The purpose of the Avifauna work unit within the Columbia River Estuary Data Development Program (CREDDP) was to determine the role of birds within the Columbia River Estuary. The study was divided into several phases to meet this objective. Initially, a literature review of previous avian research was conducted (Jones & Stokes Associates 1980). Three initial study objectives were designated (Pacific Northwest River Basins Commission [PNRBC] 1979): (1) identify "key" avian species and the habitats important to them, (2) identify key avian habitats and describe their avian species composition
